From 9ee6af9c3fad48cddc0684d0c77d3ea1329e10a1 Mon Sep 17 00:00:00 2001 From: Thomas Abraham Date: Tue, 15 May 2012 15:47:40 +0900 Subject: [PATCH] ARM: EXYNOS: Remove a new bus_type instance for EXYNOS5 A seperate bus_type instance is not required for EXYNOS5. The existing bus_type instance used with EXYNOS4 is sufficient for both EXYNOS4 and EXYNOS5. This also solves issue of uninitialized usage of exynos4_subsys in EXYNOS4 power management code that is reused for EXYNOS5 also. In addition to that, the existing exynos4_subsys bus_type is renamed to exynos_subsys to indicate that it is reused on both EXYNOS4 and EXYNOS5 platforms.
